随着智能电网信息标准化的开展,信息集成中出现的模型不匹配、语义或语法错误的问题愈显突出。由模型不一致导致的信息流阻塞逐渐成为目前信息集成和运行的瓶颈。从解决互操作过程中出现模型语义不一致,实现元数据层语义互操作,以及规范企业集成总线语义的角度出发,分析基于RDF与OWL语义的电力系统公共信息模型(common information model,CIM)信息模型校验机制。重点讨论Jena的结构与推理机制,并利用Jena提供的模型接口(RDF API)和本体接口(ontology API)开发一套模型校验工具,实现电网模型的语义级校验。最后选取两种典型案例进行应用测试。
With the development of standardization of smart grid information, the models that appear in information integration do not match each other, and the problem of semantic or grammatical errors becomes more prominent. Information flow blocking caused by model inconsistencies has gradually become the bottleneck of the current information integration and operation. From the perspective of resolving the model semantic inconsistencies in the process of interoperation, realizing semantic interoperation at the metadata layer and standardizing the semantics of the enterprise integration bus, this paper analyzes the power system common information model (CIM) information model based on RDF and OWL semantics, Verification mechanism. It focuses on the structure and reasoning mechanism of Jena, and develops a set of model verification tools using the RDF API and ontology API provided by Jena to achieve the semantic level verification of the grid model. Finally select two typical cases for application testing.
